SPECIFICATION forming part of Letters Patent No. 647,739, dated April17, 1900.

' Application filed September 9, 1899. Serial No. 730,014. (No model.)

To all whom it may concern,.-

Be it known that I, JAMES BARRETT, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Sewer-Traps and their Connections and Equipments, ofwhich the following is a description suiiciently full, clear, and exactto enable those skilled in the art to which it appertains or with whichitis most nearly connected to make and use the same.

This invention relates to sewer-traps usually included within the boundsof the walls of a dwelling, though some features, if not all, may beemployed in other places and connections. It is the object of thisinvention to provide improved means for temporarily sealing the sewageand waste-water system of a dwelling from the sewer outside when it isdesired to test the pipes or system inside or for other reasons, thesealing-gate being at other times removed, so as to allow of the freeflow of water through the pipes.

It is also the object of the invention to provide improved means forsupporting the part of the trap to which the gate or valve is hinged, soas to secure a greater readiness of adjustment and removal of parts andother advantages.

The invention consists of the improvements hereinafter more fully andparticularly pointed out.

Reference is to be had to the annexed drawings, and to the lettersmarked thereon, form ing a part of this specification, the same lettersdesignating the same parts or features, as the case may be, whereverthey occur.

Of the drawings, Figure l is a longitudinal central sectional view ofhalf of a sewer-trap embodying my improvements. Fig. 2 is a transversesectional view taken on the line 2 2 of Fig. l looking toward the gateor valve of the trap. Fig. 3 is a cross-sectional view taken through thegate and its sealing means, whereby communication with the sewer outsideand the pipe system inside is or may be cut 0E. Fig. 4 is a transversesectional view of the same. Fig. 5 is a bottom plan view of the capwhich covers the gate or slot for the reception of the gate for cuttingo the communication between the outside and the sewer-trap inside, andFig. 6 illustrates in s'ection a modified construction of cap or coverand water connection.

In the drawings, a designates the body of the trap, which is providedwith a clean-out aperture orport b, a fresh-airvent c, and 'a water orsewer port d, as also a sect-ion of pipe c, leading to the seweroutside.

The reference-letter f designates a gate or valve which controls a portg, throughwhich the sewage or water flows from the trap proper, a, tothe pipe c. The side walls of the latter where they join the body ct areprovided with slideways for the reception from above of a frame h. c.,so that the frame h may be entered from labove and slid down in thegrooves formed in the sides or walls of the trap to its seat c', whichis in the form of a flange projecting outwardly from the partitionbetween the body a and pipe e just below the port g and having aninturned portion to take over the frame h. The gate f is hinged at itsupper edge or part, as at j, to the frame 7L, as shown in Figs. 1 and 2,and said frame has an inclined seat for said gate to closeagainst.

7c designates the hand-hole, through which access is had to the gate, soas to in some respects assist in the clean out, the frame h, with thegate, being removable and insertible through said hand-hole. Thishand-hole is closed by means of a cover Z, which is secured in place bymeans of bolts and nuts passing through the margin of the cover andaflangepart of the sewer-trap, as shown, a packing m intervening betweenthe cover and the flanges of the trap. By securing the support for thegate j' in place, as described, I am enabled to do the work with lessliability of breakage and in a more economical manner and at the sametime employ nuts and bolts, as at n, to hold the upper edge of thecoverZ in place, a thing that was not feasible heretofore because of themanner in which the hinges of the gate f were connected with the wallsof the trap, which prevented the ernployment of the bolts n. at exactlythe desired points in order to secure the cover Z firmly in place.

o designates a cut-od gate or slide which is adapted to be moved downinto place in grooves or guideways p, formed in the pipe c.

IOO

l other connections in the construction and adposition, as shown in Fig.1, and a coverir,

as a flange of the gate, secured in place there-n over, with packing m'interposed, as shown. A

To insure an absolutely close joint or gastight connection between the pipe and the cover, throughthe medium of the packing m, I provide theunder facejof the cover with ribs having a V shape in cross-section, sothat 'theirang-ular edges will take into or be pressed down inthepacking m, as shown, making it im possible -for'gas to escape betweenthe cover kand the packing.` This provision on the cover fr is likewiseemployed upon'the covers Zr',

as well as the cover r2, for the clean-out'b,

land it maybe-employed at other points or 'in justment of covers for theapertures of sew'- age.AV systems.

Where pipes are to be connected with the sewer, as with fresh-air-Ventaperture c and the water-port 1,1 provide the trap'with anannularrounded groove s, so that after the conn'ecting-pipe is fitted into theporter aperture to' its seat-*say at --sealing lead maybe 4poured into4the groove s between the connecting-pipe and the trap, and so eect amore vcomplete sealing of theconnecting-pipe with the trap. This mode ofconnectingthepipe with `the trap I have ascertained by experience ismuch more efficient 'than that of tamping the lead in between theconnectingpipe andthe trap in such spaceas may be-affordedby'thevvariation in the diameters-efl the two. vIn addition to thisrelatively'vjery little leadis necessary to secure the joint connectionof the pipe with the-trap, and, again, the work can be quickly done. Y

fIt-isto be particularly noted that `the provision of thefcut-oi gate pis merely for the event of Vcutting'oftf the sewage system from the-stree't'with that of the house While the latter is being tested.- Atother times the gate will be removed 'to keep the pipe e open. It

Ywould not, however, be without the scope -o'f my improvements to otherpurposes.

.The usual 'method heretofore in vcu tting ott street-mains from thehouse system has been lthrough the medium of a Y or through the manholeb, when the pipe @was stopped by means of bricks 'and cement, such asplastero'f-p'aris, which when it becomes set or employ the gate 'p for'hardl-:ans is difficult of removal and otten'occasions a breakage ofthe pipes. avoided by, my improvements. j Iln "order to `'provide foreiicient means All this is admitting water'into the pipe system of thehouse when testing the sewer system of the house, I may provide the hubvror projection leading to the clean-out b with a projecting Y branch z,which is covered with an airtight cap when the Y branchV is not in use.rI prefer, however, to employ the nipple z',

` screwing into a boss inthe cover r', asshown in` Fig. 6, andscrew-threaded to receive a cap or a hose-coupling when a waterconnectionis to be effected for testing purposes.

The gate f acts automatically to' prevent .-the'backow of water from thestreet sewage `systeminto rthe dwelling. l

Having thus explained the nature of `the invention andv described a wayof constructing and using the same, though without attempti'n gto setforth all of the fornisin which it maybe made or all of the modes of itsuse, itis declared that what is claimed is;

1. In an apparatus of the character described, a conduit whose wallshave slideways extending from the ends of a transverse opening in oneside of the conduit; and a `cnt-oft gate constructed to pass vthroughsaid opening into engagement with said slideways, said gate havingintegral with 'it a l*cover for the opening.

2. I-n an apparatus of the character described, conduit whose walls haveslidevways extending from the ends of a transverse opening through .oneside of the conduit, the latter being flanged for-attachment of a-coverfor said opening; and -a cut-olf gate constructed to pass through `saidopening into yengagement with said slideways, said gate being flanged toform a cover for the opening, constructed to be clamped tothe hangedportion ofthe conduit. l

3. A sewer-trap provided with grooves in itswall ata point surroundingan' outletport, in combination with a one-piece frame ladapted to bereceived in said grooves and having a valve-seat, and a gate-'valve forcontrolling the outlet-port said gate-valve being hinged over said seatto' one and the same frame as that having the valve-seat.

4. A-sewer-trap comprising in its construction the trap proper having anloutlet-pipe `springing from a vertical'wall thereof and verticallygrooved inits sides'adjacent to said vwall of the trap, the latterhaving an opening `or port by which the'trap communicates with thep'ipeand also having a seat formed on its -ou'ter side just below saidopening; a sliding frame engaging the grooves ofthe outlet-pipe and theseat on the wall of the trap, said frame being apertured to registerwith the opening insaidtrap-wall andhaving an inclined valveseat; andagate or valve hingedto the said -frame so as to rest against saidinclined seat;
